ROOFING.

Specification of Letters Patent.

Patented Mar. 5, 1918.

Application filed May 1, 1916. Serial No. Edi/60.

To all w from it may concern:

Be it known that l, Evnnsr'r A. '"Wui rwon'rn, a citizen of the United States, res1ding at llncon, in the Canal Zone, Panama, have invented new and useful Improvements in Rantings, of which the following is a specification.

ln laying roofin made up 0t corrugated shingles considers. le dificulty has been experienced in providing a water-proot go nt between the sections, because when the shin glee have their adjacent edges overlapped a space is leit between certain portions of the shingles due to the thickness of the latter.

it is therefore the primary object ct this invention to provide a root covering made up oi. a plurality of corrugated sections so designed as to permit the same to be quickly and easily laid 111 a manner to provide an. absolute water tight joint between the ail-3a cent shingles, and with a saving ct material.

The nature and advantages ol the invention he better understood when the following description is taken in connection with the accompanying drawings, the nuvention residing in the construction, combination and arrangement of parts as claimed.

in the drawing forming part of this specification lilre numerals oi reference indieate similar parts in the several views and wherein:

Figure l is a plan view showing the manher in which the shingles are arranged.

Fig. 2 is a transverse sectional view.

Fig. 2 is a view of one of the sections of the first course,

hig. t is a detail view of the sections of the second course.

Fig. 5 is a detail view of one of the bridgin sections of the first course.

%ig. 6 is a view in plan of one of the bridging sections of the second and succeeding courses.

Referring to the drawing 1n detail and particularly to Fig. 3, 10 indicates a COITIL gated shingle which may be manufactured from tile, sheet iron, asbestos or any other suitable material, and may be anode of any length and width to suit the builder or manufacturer. The first course of the roof 1ndicated at A is made up of a plurality of these sections, which latter have their lower edges disposed flush with the cave line, and their and edges in contactmg engagement,

the second course indicated at B and which section is of substantially rectangular outline and has two oi": its corners cut away as at 11, the angle of the out being approximately forty-live degrees. It is to be understood that these sections can also he constructed from any suitable material. A plurality of these sections constitute the second course B and are adapted to be arranged end to end with their lower edges overlapping the adjacent edge of the first course A. With the sections thus arranged the cut away poi:- tions ll of the adjacent sections unitedly deline a crotch which is wholly disposed above adjacent edge oil the first course A and in alinenient with the meeting edges of the respective sections of the course A. As shown the crotch is substantially lI-shaped due to the result of cutting the corners away on an angle of approximately forty-five degrees, hut it is to be here understood that the outline of the cut away portions can be varied within the scope and spirit of the invention.

in Fig. 5 l have illustrated what is termed a bridging plate adapted to overlie the joint between the meeting edges of the sections 10 of the first course, while one end of this section is formed as at 16 to fit within the cut away portions of the sections of the second course, and as shown in this particular instance is substantially ll-shaped as at 1d. The section 15 is of such length as to bridge the joint between the meeting edges of the sections 10 throughout its entire length. Covering the joint defined by the J-shaped portions 14 when the latter is positioned within the crotch defined by the cut away portions 11 of the section of the second course, is a second bridging section 15* which overlies the said joint and completely covers the same. The third course of the group is made up of a plurality of sections constructed in identically the same manner as the sections 12 of the second course, and by reason of this fact the bridging section 15' has a V-shaped end portion 16 adapted to be fitted within the crotch defined by the cut away portions of the sections of the third course. The opposite end of the section 1.5

can also he made V-shaped to add to the 119 artisticness or the root construction as a on the roof determined by the surface are posed. and the dimensions or the sections of the respective courses which latter tact also regulates the number of joints hetvveen the sections. By reason or the construction and. arrangement herein illustrated and de scribed, it will he obvious that l have pro vided a roofing made up oi. a plurality out corrugated sections and rovided. tor an ahsolute water tight joint etvveen the respective sections with the saving otniaterial in consideration of the present day method in laying a roofing of this type.

While it believed that from the foregoing description the nature and advantages of the invention will be readily apparent, l desire to have it understoodthat l do not limit myselr to the precise construction and arrangement or parts herein illustrated and that sneh changes may he resorted to when antenna scope out what is comprising" a plurality or corrugated eections arranged edge to edge, the sections at the overlapping courses having their corners cut away and unitedly defining substantially it shaped crotches disposed above the adjacent course, a section hridging the joint between the first sections and having a Wehaped end fittedwithin said crotching, and an additional section overlapping the joint between the overlapping sections and said crotch and having a V-shaped lower end portion projecting beyond the lower ends or the lower overlapping" sections and having a like portion at the other end fitted. in the crotch or the sections above.

In testimon whereof it omit nay signature.
